Mr. John Fee is a retired lawyer, a senior golfer, and the author of “13PUTT: Experiences of a Duffer.” He tries to share the joy of the sport from the view of an aging golfer of mediocre talent, which makes this book closer to the majority of golfers than anything authored by a professional. The people with whom Mr. John plays are there primarily to enjoy themselves, not to earn a livelihood. Notwithstanding competitions, their common opponent is the golf course, not each other, and they appreciate their companions’ success. Like dogs off their leash, they relish the open air and green grass.
